如用SQL语句导出oracle某一用户的数据，我想通过SQL用PB程序来控制，不是在DOS下

你看看这些表有你要的相关资料：
SQL> select table_name from dict where table_name like '%PRIV%';
--此语句查询出39个权限表
SQL> desc dict;

COMMENTS                                           VARCHAR2(4000)SQL> select * from user_sys_privs;
--查看直接授予用户的系统权限(使用spool off; spool path ;selec……; 保存结果到文本)
SQL> select  *  from dict where table_name like '%PRIV%';
